최근 친환경에 대한 관심이 높아지면서 전기 자동차 및 연료전지 자동차(이하 전기 자동차라 칭함)의 관심이 높아지고 있는데 이런 전기 자동차의 특징은 연비에 관련된 규제가 기존 내연기관에 비하여 적다는 것이다.Recently, as interest in eco-friendliness has increased, interest in electric vehicles and fuel cell vehicles (hereinafter referred to as electric vehicles) is increasing. A characteristic of these electric vehicles is that there are fewer regulations related to fuel efficiency compared to existing internal combustion engines.
기존의 내연기관은 연비를 올려 버리면 질산황 및 이산화탄소 등의 환경에 나쁜 물질들이 방출되기 때문에 이에 대한 각종 규제가 있으나 전기 자동차의 경우에는 환경오염을 방지하기 위하여 만들어지는 차량이기 때문에 환경규제에서보다 더 자유로운 것이다.Existing internal combustion engines emit environmentally harmful substances such as sulfur nitrate and carbon dioxide when fuel efficiency is increased, so there are various regulations regarding this. However, in the case of electric vehicles, since they are vehicles made to prevent environmental pollution, environmental regulations are stricter than the environmental regulations. It is free.

The powertrain is a component that directly affects battery capacity, zero-back motor torque, motor output, and driving distance, and its advantage is that there is no idling vibration.
한편, 전기 자동차에서의 파워트레인을 차체 프레임에 마운팅하는 시스템은 차량의 진동 제어 및 롤링 거동을 제어하기 위한 마운팅 부재를 이용하여 3점 지지 방식으로 장착하고 있는 것으로 즉, 파워트레인의 좌측과 우측 그리고 리어에 마운팅 하는 것이나 종래 리어 마운팅 구조는 많은 문제점이 있는 것으로서 이를 상세히 설명하면 다음과 같다.Meanwhile, the system for mounting the powertrain in an electric vehicle to the body frame is mounted in a three-point support system using mounting members to control vibration and rolling behavior of the vehicle, that is, the left and right sides of the powertrain and There are many problems with rear mounting and the conventional rear mounting structure, which are explained in detail as follows.

따라서 이때에는 브라켓(20)의 사이즈를 증대시켜 사용하게 되는바 이는 중량이 무거운 브라켓(20)을 미세 조정하여 체결하는데 어려움이 따르는 문제점이 있었다.Therefore, at this time, the size of the bracket 20 is increased and used, but there is a problem in that it is difficult to finely adjust and fasten the heavy bracket 20.
또한, 종래의 마운팅 구조에서는 하나의 러버탄성체(12)를 사용함에 따라 파워트레인(40)의 구동력에 따른 구동반력 제어를 효과적으로 제어하지 못하여 절연 및 진동 저감 효과가 떨어지는 문제점이 있었다.In addition, in the conventional mounting structure, as a single rubber elastic body 12 is used, there is a problem in that the driving reaction force control according to the driving force of the power train 40 cannot be effectively controlled, resulting in poor insulation and vibration reduction effects.

이와 같은 본 발명은 전기자동차용 파워트레인의 후미를 차체 프레임에 장착하는 리어 마운팅 구조에 있어서, 일측에는 차체 프레임(100)에 볼트(210)로 체결되기 위한 체결홀이 다수 구비되고, 중앙에 탄성체홀이 구비되는 프레임측 브라켓(200); 진동 저감 및 절연 기능을 발휘하도록 러버가 씌워진 부시가 중앙에 구비되어 프레임측 브라켓(200)의 탄성체홀에 장착되는 제1러버 탄성체(300); 일단에는 파워트레인(400)에 볼트(510)로 체결되기 위한 체결홀이 구비되고, 타단에 탄성체홀이 구비되는 파워트레인측 브라켓(500)으로 구성된다. In this invention, in the rear mounting structure for mounting the rear of the powertrain for an electric vehicle to the car body frame, a plurality of fastening holes for fastening to the car body frame 100 with bolts 210 are provided on one side, and an elastic body is located in the center. A frame side bracket (200) provided with a hole; A first rubber elastic body (300) having a rubber-covered bush at the center to reduce vibration and provide insulation functions and being mounted in the elastic hole of the frame side bracket (200); It is composed of a powertrain side bracket 500, which has a fastening hole for fastening to the powertrain 400 with a bolt 510 at one end and an elastic hole at the other end.
또한, 진동 저감 및 이중 절연기능을 발휘하도록 러버가 씌워진 부시가 중앙에 구비되어 파워트레인측 브라켓(500)의 탄성체홀에 장착되는 제2러버 탄성체(600); 양단이 상기 제1러버 탄성체(300)의 부시와 제2러버 탄성체(600)의 부시에 볼팅 체결되어 프레임측 브라켓(200)과 파워트레인측 브라켓(500)을 연결하는 연결로드(700);로 구성된다.In addition, a second rubber elastic body 600 is provided with a rubber-covered bush at the center to reduce vibration and exhibit double insulation functions and is mounted in the elastic hole of the powertrain side bracket 500; A connecting rod 700, both ends of which are bolted to the bush of the first rubber elastic body 300 and the bush of the second rubber elastic body 600, to connect the frame side bracket 200 and the powertrain side bracket 500; It is composed.
이러한 본 발명은 구동모터와 인버터 및 감속기가 조합된 파워트레인(400)의 리어를 마운팅 구조에 의해 지지되게 한 것은 종래와 마찬가지이다.This invention is the same as the prior art in that the rear of the powertrain 400, which is a combination of a drive motor, an inverter, and a reducer, is supported by a mounting structure.
그러나 본 발명에서의 특징은 파워트레인(400)을 마운팅하기 위한 브라켓을 차체 프레임(100)에 체결되는 프레임측 브라켓(200)과 파워트레인(400)에 체결되는 파워트레인측 브라켓(500)으로 구분 제작하되 프레임측 브라켓(200)에는 제1러버 탄성체(300)를 파워트레인측 브라켓(500)에는 제2러버 탄성체(600)를 장착한 것이다.However, a feature of the present invention is that the bracket for mounting the powertrain 400 is divided into a frame side bracket 200 fastened to the car body frame 100 and a powertrain side bracket 500 fastened to the powertrain 400. It is manufactured by attaching the first rubber elastic body 300 to the frame side bracket 200 and the second rubber elastic body 600 to the powertrain side bracket 500.
즉, 차체 프레임(100)에는 프레임측 브라켓(200)을 파워트레인(400)에는 파워트레인측 브라켓(500)을 각각 설치하기 때문에 종래의 브라켓에 비해 중량이 가벼워 그만큼 미세하게 조정하여 체결할 수 있는 것이며, 제1러버 탄성체(300)와 제2러버 탄성체(600)에 의해 파워트레인(400)의 구동반력에 따른 구동반력을 이중으로 제어하여 절연 및 진동 저감 효과가 증대되어 그만큼 탑승자들의 승차감을 향상시킬 수 있는 것이다.In other words, since the frame side bracket 200 is installed on the car body frame 100 and the powertrain side bracket 500 is installed on the powertrain 400, the weight is lighter than the conventional bracket and can be fastened with fine adjustment. By doubly controlling the driving reaction force according to the driving reaction force of the powertrain 400 by the first rubber elastic body 300 and the second rubber elastic body 600, the insulation and vibration reduction effects are increased, thereby improving the riding comfort of passengers. It can be done.
이와 같은 본 발명은 상기 프레임측 브라켓(200)에는 차체 프레임(100)에 볼트(210)로 체결될 수 있도록 체결홀(도면 중 미도시)이 다수 형성되고, 중앙에는 탄성체홀(도면 중 미도시)이 구비되어 있고, 파워트레인측 브라켓(500)에는 파워트레인(400)에 볼트(510)로 체결될 수 있도록 체결홀(도면 중 미도시)과 탄성체홀(도면 중 미도시)이 구비되어 있다.In the present invention, the frame side bracket 200 is formed with a number of fastening holes (not shown in the drawing) so that it can be fastened to the car body frame 100 with bolts 210, and an elastic hole (not shown in the drawing) is formed in the center. ) is provided, and the powertrain side bracket 500 is provided with a fastening hole (not shown in the drawing) and an elastic hole (not shown in the drawing) so that it can be fastened to the powertrain 400 with a bolt 510. .
상기 프레임측 브라켓(200)에 형성된 탄성체홀에는 제1러버 탄성체(300)가 장착되고, 파워트레인측 브라켓(500)의 탄성체홀에는 제2러버 탄성체(600)가 장착되는데 상기 제1러버 탄성체(300)와 제2러버 탄성체(600)는 각각 러버가 씌워진 부시가 중앙에 구비되어 있어 그만큼 더 진동 저감 및 이중 절연 기능을 발휘할 수 있다.A first rubber elastic body 300 is mounted in the elastic hole formed in the frame side bracket 200, and a second rubber elastic body 600 is mounted in the elastic hole of the powertrain side bracket 500. The first rubber elastic body ( 300) and the second rubber elastic body 600 each have a bush covered with rubber in the center, so they can further reduce vibration and exert double insulation functions.
또한, 연결로드(700)를 구비하여 일단은 제1러버 탄성체(300)의 부시에 볼팅 체결하고, 타단은 제2러버 탄성체(600)의 부시에 볼팅 체결하여 프레임측 브라켓(200)과 파워트레인측 브라켓(500)이 연결로드(700)에 의해 서로 연결되게 한다.In addition, a connecting rod 700 is provided, one end of which is bolted to the bush of the first rubber elastic body 300, and the other end of which is bolted to the bush of the second rubber elastic body 600 to connect the frame side bracket 200 and the powertrain. The side brackets 500 are connected to each other by the connecting rod 700.
즉, 파워트레인(400)의 구동력에 의한 구동반력을 제1러버 탄성체(300)와 제2러버 탄성체(600)에 의해 이중으로 제어되어 그만큼 더 절연 및 진동 저감효과가 증대되어 탑승자들의 승차감을 더욱 향상시킬 수 있는 것은 물론 프레임측 브라켓(200)과 파워트레인측 브라켓(500)을 차체 프레임(100)과 파워트레인(400)에 각각 체결하기 때문에 중량이 가벼워 미세하게 조정하여 체결할 수 있는 것이다. In other words, the driving reaction force caused by the driving force of the powertrain 400 is doubly controlled by the first rubber elastic body 300 and the second rubber elastic body 600, so that the insulation and vibration reduction effects are further increased and the riding comfort of the passengers is improved. Not only can it be improved, but because the frame side bracket 200 and the powertrain side bracket 500 are respectively fastened to the car body frame 100 and the powertrain 400, the weight is light and can be fastened with fine adjustments.
여기서 상기 연결로드(700)는 파워트레인측의 제2러버 탄성체(600)에서 프레임측의 제1러버 탄성체(300)로 작용할 수 있도록 구동반력의 접선방향을 향하도록 배치하여 구동반력 제어에 보다 더 유리한 것이다.Here, the connecting rod 700 is arranged to face the tangential direction of the driving reaction force so that it can act from the second rubber elastic body 600 on the powertrain side to the first rubber elastic body 300 on the frame side, thereby improving the driving reaction force control. It is advantageous.
또한, 본 발명에서는 상기 연결로드(700)를 프레임측 브라켓(200)과 파워트레인측 브라켓(500)의 양쪽면에 장착되도록 좌,우 한 쌍으로 구성하되 중앙에 연결부(710)를 구비하여 한 쌍의 연결로드(700)가 함께 작동되게 하여 그만큼 더 구동반력 제어가 향상되어 절연 및 진동 저감 효과가 향상된다.In addition, in the present invention, the connecting rod 700 is configured as a pair of left and right sides to be mounted on both sides of the frame side bracket 200 and the powertrain side bracket 500, and is provided with a connection portion 710 in the center. By allowing the pair of connecting rods 700 to operate together, the driving reaction force control is further improved, thereby improving the insulation and vibration reduction effects.
